To all whom it may concern: A

Be it known thatI; AfnansohT M.,PoND, a

citizen ofthe United States, anda resident of the city of Dubuque, in thecounty of Dubuque and State of Iowa, have invented vcertain newand useful Improvements in Grease- Cups; and 'I do hereby declare that the following is a full, clear, and exact descrip tion of the same, reference being had'toy the accompanying drawings, and to the numerals of reference marked thereon, which' form a part of this specification.

This invention relates to an improved type of quick adjustable grease cup adapted for any purpose wherein the cap of the grease cup may be operated inwardly by either a direct movement or rotational adjustment lon the base. However, the cap may only be removed"^-from the base by ,an unthreading operatiomthus obviating possibility of loss ofthe cap. y f

It is an ob ect therefore of this invention to construct a greasefcup provided with a cap which may be positively thrust inwardly on the base'Y of the devicey without rotational movement, or rotated to thread the same 4inwardly upon thevbase. y Y n L It is also an object f this invention to con.- struct a grease c'upcomprising a threaded base, and a capI provided with resilient toothed members threads of the base whereby the cap may be threaded on or oli the base, as well as thrust inwardly without rotation upon said base dueto springing ofy said toothed members over the threads,`thus permitting' rapid ad iustment of' the cap upon the base. It is furthermore an object of this invention to construct a quickly adjustable grease cup device wherein co-acting resilient members are providedbetweenthe base and cap.

' of the device permitting quickadiustment of the cap upon thebase, and yet necessitating af rotational threading vmovement thereof to detach the cap from'the base.

Other 'and furher imprtantnobiectsiof this ,invention will 'be levident'ffifointhe disclosure in the drawings and specification.

As shown on the drawings: v

The device comprises a conventional'tubular base member 1, the lower end "of which is'threaded to permit attachment thereto into a mechanism to be lubricated, and provided `with threads 3, onthe yupper portion thereof.

The cap for the grease cup Aconsists of a metal 'shell or casing 4, into which the lubricant is packed,'andsecured on the interior of y said capis a U-shapedresilientgstrap 5,se-

k,cured in -place by a central rivet 6, `with the -ends Yof lsaid -strapfbentvin'wardly to afford engaging teeth 7, for c0-action with the threads 3, of the base member 1; The cap 4, is stamped or otherwise .formed outwardly, as denoted by the reference numeral 8, 'at the points in the side walls registering with the lower ends ofthe strap 5,

to permit the'lower ends thereof on which the teeth 7, are provided to spring outwardly over the threads 3, of the base, when the cap is thrust inwardly. Y.

In the form of device illustrated in Figs.

I5', (i` and 7, the base memberl, as yshown on 1 the .previous construction is used, 'having the exterior4 upper threads *3,rand the lower exl' terior threads 2; The cap member, however,

is off slightly diliz'erent construction, and is y denoted as a whole bythe reference numeral '9. on'opposite sides thereof, the walls .areSIOt- Near the lower f endv of the 1 cap member ted totafford Yintegral resilient members 10,

i which,` at theirL lower ends,` are lprovided Y "with engaging teethy 11, for"co'-acti`onwith which is interiorly threaded as denoted by the reference numeral 13, and the base member denoted as a Whole by the reference numeral 14, is constructed as hereinafter described to receive the cap member Vengaged therewith. The upper portion ofthe base Ymember 14, on "each'side is provided with vertical slots diametrically'disposed on 'the exterior surface, and mounted in each thereoffa're resilient-members 15 the upperr ends of which extend above the upper end of the base member and are provided with 'outwardly formed toothed members 16, for co- -action'with interior threads 13, of the cap 12.

The operation is as follows:. In the `form of device illustrated in Figs, 1 to 4, inclusive, if it is desired to vattachy or adjust ythe cap `4, inwardly uponthe base 1, of the device, the cap is merely thrust inwardly'under pressure, thereby causing the inclined toot-hed members 7, to ride over the .threads 3, of the base 1, until the desired Y point of adjustment of the cap has been reached, that is, after a certain quantity of the lubricant contained within the cap 4, has been forcedthrou'gh the base 1, to the mechanismV tobe lubricated. In the event that the lubricant should have become harfdened so as to resist easy adjustment inlwardly of the cap 4, under pressure, the cap4, may be rotated, thereby screwing the cap 4, upon the base 1, with the toothed members 7, engaging and co-acting with the threads 3, for the purpose, thus obtaining a pconsiderable leverage. effect to forceV the -.grease from the device into the mechanism. A.I-IoWever, in order-to detach the cap '4, from '.therdevice, it is necessary to rotationally adjust 'the same, thereby unthreading the cap 40 .fromthe base. The Vnecessity for this operation precludes Vloss of the cap from the device.

JInj-the formof device illustrated in Figs. 5 to 7, inclusive, the operation is identical, 'the only 'difference being that rthe resilient members 10, provided `with the engagingV :teeth 11, for co-action with the threads 3, of lthe base, are formed integral with themetal .Cap 9. iv jr l Y In the form ofdevice illustrated in Figs. 8 top10, inclusive, I have shown thetoothed resilient members associated with the base member 14, of the device, ,andl withthe interior of the cap 12, lthreaded for co-action therewith. In this construction,a's in the preceding constructions described, the cap .may be adjusted inwardly upon thebase 14, either `'by jthrustingthe same inwardly and Y acausing the toothed members 4to click. `over 30 the threads 13, or by rotational adjustment `Yofthe ,cap 12, to thread the. samev inwardly upon the base members by co-action with said resilient .toothed members. Likewise, in VVorder to ,detach the. cap from the device ift issnecessary `-to Akrotate the same ,to iin- `being inserted on accidental detachment and .pass over lmembers together and which yis adapted fto thread the cap from engagement with the toothed members 16. Obviously, the device is susceptible of many other modlications V- not shown, andpI therefore do not purpose limiting the patent granted except as necessitated by the prior art.
